Description

This is Decade and Binary Counter.

Each of these monolithic counters contains four master slave flip-flops and additional gating to provide a divide-by two counter and a three-stage binary counter for which the count cycle length is divide-by-five for the 90A and divide by-eight for the 93A.

All of these counters have a gated zero reset and the 90A also has gated set-to-nine inputs for use in BCD nine’s complement applications.
